DataDoe does not fetch vendor codes from Amazon. You upload them as a CSV file. Uploaded vendor codes are added to vendor views that contain SKU or ASIN, such as [Vendor Sales, Traffic & Inventory](/hub/data-scheme?source=VENDOR_CENTRAL). ## Where do I upload Vendor Codes? 1. Open [Sellers & Vendors](https://app.datadoe.com/sellers-and-vendors). 2. Select a vendor. Vendor Codes upload is available for vendors only. 3. Go to **Upload Vendor Codes** and choose your file. ## What is the file format? You can [download a sample CSV](https://app.datadoe.com/sample-files/vendor-codes.csv). | Column | Required | Description | | ------------- | -------- | ----------------------------------- | | `child_asin` | See note | Product ASIN (10 characters). | | `sku` | See note | SKU this vendor code applies to. | | `vendor_code` | Yes | The vendor code assigned by Amazon. | Each row must contain exactly one of `child_asin` or `sku` — never both, and never neither. Rows that don't follow this rule are rejected. ## Re-uploading Vendor Codes When you upload a Vendor Codes CSV, DataDoe matches each row on the seller or vendor account, plus whichever of ASIN or SKU is present in that row. - **Matching row** → the vendor code is overwritten with what is in the file. - **No match** → a new row is added. ## Which tables use uploaded Vendor Codes? Look for tables that contain the `vendor_code` column in the [Data Scheme](/hub/data-scheme). ## Need help?
